FORT LAUDERDALE — A Fort Lauderdale father is working with a police sketch artist who will try to draw an image of the bicyclist who bashed his adult son's head with a baseball bat during an argument, leaving him in critical condition.

Joseph Watson, 71, said he met with the artist Thursday.

His son — Virlyn Watson, a 49-year-old father of two — was still at Broward General Medical Center on Thursday, more than a week after a man hit him in the head twice with an aluminum bat on Feb. 10.

Doctors said the left side of the victim's face will be paralyzed if he survives, Joseph Watson said.

"He cracked his skull and fragments went into his brain," Watson said. "It was so cruel and vicious."

The bicyclist argued with his son because he was upset that they had parked their Chevy pickup on the sidewalk, Watson said. According to a police report, the bicyclist threw a rock at the truck. Virlyn Watson threw a baseball bat at the man and missed. The man then picked up the bat and hit Virlyn Watson.

Surveillance video at a nearby store showed the suspect fleeing from the 2800 block of Northwest 19th Street.

He is described as being 18 to 22 years old and 5 feet 7 inches tall, police said.

Police ask anyone with information about the incident to call Detective Donald Gauntner at 954-828-5527 or Broward County Crime Stoppers at 954-493-TIPS.
